Norepinephrine (Alpha1,2 and beta 1) 682 What type of neurological blockade would hexamethonium create? Hexamethonium is a nicotinic antagonist, and thus is a ganglionic blocker. 683 What would be the effect on blood pressure with infusion of the alpha -2 ago nist clonidine? Initially vasoconstriction would increase bp, but then it acts on central alpha2 receptors to decrease adrenergic outflow resulting in decreased bp. 684 What would be the next drug that you would give and why Pralidoxime, regenerates active cholinestrase 685 Which antimuscarinic agents are used in producing mydriasis and cycloplegia? atropine, homatropine, tropicamide 686 Which drug increases Sys BP w/o affecting Pulse Pressure Epinephrine 687 Which of epi, norepi, or isoproterenol results in bradycardia?

Also useful if you have open angle glaucoma, a sthma, or hypotension. 692 Why are albuterol and terbutaline effective in tx of acute asthmatic attacks ? These B-2 agonists cause respiratory smooth muscle to relax. [snip] Why does atropine dilate the pupil? Blocking muscarinic receptors in the circular fibers of the eye, results in unop posed action of radial muscles to dilate. 694 Why does NE result in bradycardia? NE increases bp, which stimulates baroreceptors in the carotid sinus and the aor ta. The CNS signals through vagal stimulation to decrease heart rate. 695 Why is carbachol and pilocarpine useful in treatment of glaucoma? They activate the ciliary muscle of the eye (open angle) and pupillary sphincter (narrow angle). 696 Why is pyridostigmine effective in the treatment of myasthenia gravis? As an anticholinesterase it increases endogenous ACh and thus increases strength . 697 Why is reserpine effective in treating HTN? Reserpine inhibits dopamine transport into vesicles, attenuating its conversion to NE by dopamine beta-hydroxylase. 698 Why is there a drop in systolic, mean, and diastolic bp with infusion of iso proterenol? Stimulating beta receptors stimulates heart rate, but beta receptor induced vaso dilation reduces peripheral resistance. 699 Why would a patient with cog-wheel rigidity and a shuffling gait be given be nztropine? Parkinson patients benefit from antimuscarinic agents through its inhibitory act ion within the indirect pathway. 700 Why would dopamine be useful in treating shock? Receptors = D1=D2>beta>alpha, thus increasing heart rate (beta) and blood pressu re (alpha vasoconstriction) while maintaining kidney perfusion (dopamine recepto rs) 701 Why would you give a drug like pancuronium or succinylcholine? Useful in muscle paralysis during surgery or mechanical ventilation. 702 Why would you use pralidoxime after exposure to an organophosphate? Pralidoxime regenerates active cholinesterase. 703 Will Hemicholinum affect the release of stored Ach during Cholinergic Stimul ation No, hemicholinum block the uptake of Choline and thus Ach synthesis 704 Would blockade of muscarininc receptors in the bladder be useful in treating urinary retention? No. Atropine is used to reduce urgency in mild cystitis. So it would aggravate t he urinary retention. 705 Would Hexamethonium be an effective substitute No, hexamethonium targets Nicotinc receptors and will block Parasym, Sym, as wel l as Somatic systems 706 You tx your pt with halothane as well and he has also developed malignant hy pothermia, what drug can you give

Dantrolene 707 Your patient develops a marked arrythmia due to a prolonged depolarization, can you tx this w/ Neostigmine No cholinesterase inhibitors will potentiate the stimulating action of Succinlyc holine 708 Your patient has acute angle glaucoma, does this affect your tx Yes, Scopolamine would antagonize his glaucoma 709 Your patient wants an effective drug to treat his motion sickness, what woul d you prescribe Scopolamine

-------------------------------------------------------------------------------1 A common side effects of Infection treatment is? Neutropenia Neutropenia: a condition of the blood, in which your white blood cells have a lo w count of neutrophils. Neutrophils, a type of white blood cell, is part of your body s immune system, and it helps fight off bacterial infections. When you have neutropenia, you are at greater risk of infections, and your body is not well-eq uipped to fight back. Neutropenia is a common side effect of chemotherapy and radiation for breast can cer. Because both kinds of treatment can destroy white and red blood cells, it i s important to take a Complete Blood Count test (CBC) often during your treatmen t. A CBC will reveal the count of different kinds of blood cells. Treatments include Neulasta or Neupogen (filgrastim), both of which can stimulat e white blood cell production.

Atrial and ventricul ar. 277 class IB- clinical uses? post MI and digitalis induced arrhythmias 278 class IB- effects? decrease AP duration, affects ischemic or depolarized Purkinje and ventricular s ystem 279 class IB- toxicity? local anesthetic. CNS stimulation or depression. CV depression. 280 class IC- effects? NO AP duration effect. useful in V-tach that progresses to V-fib and in intracta ble SVT LAST RESORT 281 class IC- toxicity? proarrhythmic 282 class II- effects? decrease the slope of phase 4, increase PR interval (the AV node is particularly sensitive) 283 class II- mechanism? blocking the beta adrenergic receptor leads to decreased cAMP, and decreased Ca2

+ flux 284 class II- toxicity? impotence, exacerbation of asthma, CV effects, CNS effects, may mask hypoclycemi a 285 Class III- effects? increase AP duration, increase ERP, increase QT interval, for use when other arr hythmics fail 286 class IV- clinical use? prevention of nodal arrhythmias (SVT) 287 class IV- effects? decrease conduction velocity, increase ERP, increase PR interval 288 class IV- primary site of action? AV nodal cells 289 class IV- toxicity? constipation, flushing, edema, CV effects (CHF, AV block, sinus node depression) , and torsade de pointes (Bepridil) 290 classes of antihypertensive drugs? diuretics, sympathoplegics, vasodilators, ACE inhibitors, Angiotensin II recepto r inhibitors 291 clinical use? angina, pulmonary edema (also, erection enhancer) 292 clinical use? CHF, atrial fibrillation 293 contractility? increase (reflex response) 294 contractility? decrease 295 contraindications? renal failure, hypokalemia, pt on quinidine 296 decrease Digitoxin dose in renal failure? NO 297 decrease Digoxin dose in renal failure?

YES 298 Digitalis- site of action? Na/K ATPase 299 Digoxin v. Digitoxin: bioavailability? Digitoxin>95% Digoxin 75% 300 Digoxin v. Digitoxin: excretion? Digoxin=urinary Digitoxin=biliary
